DOAC
Perioperative bleeding risk does not appear to differ among DOAC medications
predictable PK & PD
peak effects occurring 2 to 3 hours after DOAC intake
Elimination half-lives of factor Xa inhibitors (apixaban, rivaroxaban, andedoxaban) are 8 - 12h in patients with a CrCl above 30mL/min.
Dabigatran
- higher dependence on kidney clearance
- Elimination half life
- CrCl >50ml/min → 10 - 14h
- CrCl 30-49.9ml/min → 18 - 24h
because the typical length of DOAC cessation perioperatively is short (eg, 2-4 days), the risk of thromboembolism associated with DOAC cessation in the perioperative period is low (eg, <0.5%)
DOACs are not recommended for use in pregnant or breastfeeding individuals becausetheycrosstheplacentaandarepresentinbreast milkandthere are insufficient data about their safety for the fetus andnewborn
